The former world No5 allegedly breached rules in matches at four tournaments including the 2009 World Championship.

The World Professional Billiards and Snooker Association said it had considered “a large amount of material” before taking action against the player.

The sport’s supremo Barry Hearn, 64, has previously said life bans would be enforced for any player found guilty of match-fixing.

Lee, 38, of Trowbridge, Wilts, ranked No13, has been suspended from the game since October 12. His appeal against the temporary ban, made later the same month, was rejected.

It is understood the allegations relate to illegal gambling.

An investigation into suspicious betting on Lee’s Premier League match with John Higgins on October 11 last year is ongoing. There is no suggestion that four-time world champion Higgins, 37, is involved in any wrongdoing.

Lee’s lawyer Tony Miles said: “Stephen has always sought to uphold the highest standards as required of such a player.

“Stephen wishes it to be clearly known that he denies all allegations brought against him by the WPBSA. He does not accept that he has been involved in any breaches of the rules and regulations.”

The allegations relate to two matches at the 2008 UK Championship, one 2009 China Open contest, a single game at the 2009 World Championship and four clashes at the 2008 Malta Cup.

The WPBSA said: “The case will be heard at a formal independent hearing arranged by Sport Resolutions UK at a date to be arranged.”
